I don't think the ML stereo is offered in the fsport series 2, unless i'm wrong. I Def like like my 350 with the ML stereo system though worth the extra money I think. Also the Resale value of a 350 would be better than the 300. Just cause of the 350 badge on the back

 

You are correct, ML only offers in F Sport 3 for the 300 but then the F sport 3 is taken away for 2017 in Canada so no more ML option for the IS300 haha.

 

Does anyone know of a vendor or shop that is making a flash tuner for 2017 model year IS300?

 

RR racing claims with just their tune. They can enhance the is300 by 35hp and 18-35 torque
Havent read much into OV. Also up the shift limit to 7200
Hope you find what you want!! Ill be purchasing the rr here in the next couple weeks!!

 

Thanks for your response VonHoken7. I don't see anything available for the 2017 model year on their website. Did I miss something?

 

No you are correct so sorry. They havent made one for the 2017. They offer up to 2016! Sorry again

 

Hi, we certainly can flash the 2017 IS300, the only issue is that our OBD programmer does not work on the 2017MY cars, so you would have to send us your ECU for bench programming, or come to our shop.

we are working on solving the issue with the OBS tuner, but not sure when that will be available.

I think I'll wait until the tuner is available. I would like to have the ability to remove the tune for warranty purposes. Thanks.

 

I have a 2016 IS300 F-sport and want to get the full horsepower as well. Sucks being neutered haha. I'm new to this stuff, if you "remove the tune" won't the dealership still see that it was flashed or programmed at some point? Seems like with modern technology would get you caught messing with the cars computer. I bought mine at the Lexus dealer with low miles and purchased an extended warranty, I'm really nervous to void my warranty.

P.S. Sicko2017 where are you located in TN? I live in M'boro and bought my IS300 at Lexus of Nashville this past Friday

 

I'm in east TN near Kingsport. Ditto on being nervous about voiding my warranty.

 

wouldent you be able to reflash back to stock before going to the dealer? like a cobb accessport?
i doubt it will affect warranty, i did scan my friends tuned is350 no problems on techstream.

 

very grey area ...if you gonna play u gonna pay

 

Nobody currently offers a handheld tuner for the 2017 model year cars. I would have to mail my ECU back to the vendor every time I needed to flash it back to stock.

 

Here is the bottom line, if you tuned a 2017 IS300 to IS350 specs the dealer would have no way of knowing. The only possible way to detect it is if you notice the higher rev limit, so we can easily keep the rev limit stock.

In any case, engine problems with these cars, especially during warranty period are unheard of. We have been running our shop 2014 IS350 supercharged with 360+whp for nearly 8000 hard miles now without a single hiccup. We have tuned 100's of ISF's (some of which are high mileage) and RCF's without a single reported engine failure, EVER!

Just got my 2017 IS300 AWD non-Fsport ECU tuned by RR-Racing. My car is basically stock with an F-Sport intake and the tune simply turned it from a 300 to a 350. I won’t go into the details of the tune since you can get more info from RR-Racing website or just call them up.

Fortunately I’m somewhat local (2 hours drive to their shop), but if you live far away you will need to send in your ECU since the current handheld doesn’t work with 2017 model. Anyway, it’s definitely worth the money since the cost difference of a 300 AWD and 350 AWD is roughly about $3,335 (for my area). I would take Uber for a few days and send in my ECU if I live far away...but that’s me.

Anyway, I’ll try to leave more feedback once I drive it more but the car pulls harder and smoother throughout the first 3 gears. Hopefully I can hit the track to get some 1/4 mile time soon.

Thank you Rafi, Simon, and the RR-Racing crew for making this possible.
